IMPROVEMENT IN PROGRAMME-CLOCKS.

Specification forming part of Letters Patent No. 143,230, datedSeptember 30, 1873 application filed May 10,1873.

To all whom it may concern:

Be it known that 1, SAMUEL F. EsTELL, of the city of Chicago and Stateof Illinois, have invented a new and useful Improvement inProgramme-Clocks, of which the following is a complete specification,reference being had to the accompanying drawings.

My improvement embraces a modification of myinventions relating toprogramme-clocks, for which Letters Patent of the United States werefirst granted to me January l1, 1870, No.

98,678, and has for its object the locating of the programme-wheelbeneath the movements77 in a more convenient and accessible position,instead of at the rear ofthe move- Fig. 2 is a attached to a sleeve, I,which latter is rigidly Y 'secured to a plate, I), at the back of theclockcase. On the sleeve, to which wheel m is attached, is a wheel, H,gearing with a pinion on the upright shaft e. A pinion on the upper endof shaft e gears with a wheel on the minute-wheel shaft F. A connectionis thus made between the movement ofthe clock and wheel m, by which thelatter is operated, regard, ofcourse, being had to the sizes of saidwheels and pinions, so that wheel m shall receive a proportionate speed.

The programme-wheel, in its position herein described, operates thestriking movement of the clock by means of a tripping-lever, C. Le ver Cis pivoted at D to a bearing secured to the back of the case, and, asshown by Fig. 2, forms an angle to accommodate it to both the wheel mand thedrop-wire. The end of 'said lever C, in contact with wheel m, isso shaped as to be tripped by the tripping-wires or springs of wheel'm.The other end of said lever C is attached to the drop-wire c of theclock, and thus at each passage of a tripping-spring, beneath the end oflever C, the strikingtra-in is putin motion.

Having thus fully described my said invention, what I claim is Incombination with a programmewheel, the lever C and drop-wire a,operating substantially in the manner described, and for the purpose setforth.

SAMUEL F. ESTELL.
